I thought this example of a picture advertisment on movieforum.com was really harmless, it's a banner that is really clearly demarcated and fits into the format of the forum, like the advertiser posted it themselves. Maybe having 1 at the bottom of every other thread could be a great revenue source for our projects.

Well, why does it have to be a company necessarily?
Maybe we can have have an ad for TVA's store?
This also gives me the idea of adding the links to our YouTube and Discord somewhere. Maybe also Twitter feed?
